Recommendation: Monitor — no exploitation signal at the moment.
A heap buffer overflow vulnerability exists in the Jansi JNI "ioctl()" wrapper due to a lack of size verification for the argument array before the system call. This can lead to heap corruption and application crashes (DoS).
All versions are believed to be vulnerable. This project is unmaintained at the time of CVE assignment.
